A Study to Evaluate Safety, Acceptability, Pharmacokinetics, and ex Vivo Pharmacodynamics of TMC278 Long Acting Formulation in HIV-1 Seronegative Participants

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.

The purpose of this study is to evaluate the safety, acceptability, pharmacokinetics (what the body does to the medication), and ex vivo (tested outside the body) pharmacodynamics (what the medication does to the body) of TMC278 long acting (slowly effective after initial dosage and maintaining its effects over a long period of time) when administered as an intramuscular (ie, in to the muscle) injection in adult participants who are seronegative for human immunodeficiency virus type 1 (HIV-1).

Phase 1

Detailed Description:

This is an open-label (all people know the identity of the intervention), multi-arm (more than one treatment group), dose-ranging study (clinical study where different doses of study medication are tested against each other) to evaluate the safety, acceptability, pharmacokinetics, and ex vivo pharmacodynamics of a single and multiple intramuscular injections of long acting TMC278 to human immunodeficiency virus type 1 (HIV-1) seronegative (having a negative serum reaction) male and female participants. The study consists of 3 phases including screening phase, treatment phase, and the follow up phase (approximately 4 to 6 months after the first dose of study medication). In treatment phase, enrolled participants will be divided in to 2 arms, ie, Arm A (female participants) which will be further divided in to Arm 1A, Arm 2A, Arm 3A, Arm 4A, and Arm 5A with 12 female participants per arm; and Arm B (male participants) which will be further divided in to Arm 1B, Arm 2B, Arm 3B, Arm 4B, and Arm 5B with 6 male participants per arm. Safety evaluations will include assessment of adverse events, clinical laboratory tests, electrocardiogram, physical examination, and vital signs which will be monitored throughout the study. The total duration of study for each participant will be approximately 5 to 7 months.

Female participants will receive a single dose of long acting TMC278 1200 mg intramuscularly (IM) at baseline (Day 0) in Arm 1A.

TMC278 long acting will be administered IM to the participants as follows: a single dose of TMC278 600 mg will be administered at baseline in Arm 2A and Arm 2B; at Months 2 and 4 in Arm 5A and Arm 5B. A single dose of TMC278 900 mg will be administered at Months 2 and 4 in Arm 4A and Arm 4B.
